or insufficient.
Faulty thermostat. Test and replace if necessary.
Automatic reset high limit control cali-
bration defective. Replace high limit.
Dirty air filter. Clean or replace.
Dirty evaporator coil. Clean as necessary.
Blower motor operating intermittently,
rotating slowly, or not at all. Check free rotation of the motor shaft. Check voltage to the
motor. Check motor capacitor. Check for miswiring. Motor
may be seizing internally
– if so, replace motor.
Water drips from unit.
Sleeve not properly pitched. Check sleeve for the required pitch down from indoor to out-
door side and level side-to-side. Readjust as required.
Condensate drain clogged. Clean condensate drain tube.
Evaporator drain pan damaged or
improperly mounted. Inspect, realign, or replace drain pan as required.
Unusually high moisture content in the
indoor/or outdoor air. Under certain ambient conditions, excessive condensate
can be generated, beyond the capacity for the unit to reject
via evaporation to the outdoor air stream. If objectionable or
frequent, connect to an internal drain system with available
optional drain kit.
Drain holes plugged in bottom edge of
base pan on outdoor side (heat pump
only). Inspect and clear blockage.
